Isphording, Ingo Eduard; Piopiunik, Marc; … - 2015
This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

Bahar, Dany; Rapoport, Hillel - 2016
Do migrants shape the dynamic comparative advantage of their sending and receiving countries? To answer this question we study the drivers of knowledge diffusion by looking at the dynamics of the export basket of countries, with particular focus on migration. The fact that knowledge diffusion...

Firm-productivity and export under non-constant marginal costs
Mukherjee, Arijit - 2016
Recent theoretical research shows that exporters are more productive than nonexporters. We show that this result holds almost trivially for the case of constant marginal cost of production, as mainly assumed in the literature, but it may not hold true if the marginal cost is not constant. Our...
